Never needed to turn WiFi off before...

Not saying it couldn't be the problem here yet, but I'm trying something else today to see if there is improvement.
[Nexus One Q&A, Help & Troubleshooting] ngy:
for me, i'm having issues with pretty much every rom saying my display is eating a huge chunk of the battery (more than 25%). every rom aside from NXsense v1.26. I've tried 2.3.3, i've tried miui, everything says display eats up a lot... but on nxsense, it says that display is only eating about 7%. whats up with that?
[Nexus One Q&A, Help & Troubleshooting] gdarren:
wifi always on solved it

Just wanted to report back that the only thing that truly made a difference for me was having wifi always on or off entirely.

Until a permanent fix is found, this is the workaround.
[Nexus One Q&A, Help & Troubleshooting] rhmorgan:
What do you mean by having wifi always on or off? Does the switching of wifi from off to on or visa versa cause the battery drain? Or, is there a way to disable wifi even more so then unchecking it in settings?
[Nexus One Q&A, Help & Troubleshooting] gdarren:
I meant that you can either uncheck wifi so that it is never on, or you can go into the advanced wifi settings and select "Never" for the wifi sleep policy. I tried the other two options for wifi sleep policy and it made no difference.

I still have, and have had, GPS on and Latitude doing whatever it does. The only change I had to make was to the wifi sleep policy and my battery life is much, much better (65% after 12 hours on battery with normal usage).
[Nexus One Q&A, Help & Troubleshooting] jamesyb0i:
I have no issue w/ wifi because I don't use it except when at home while being charged.

My theories are

1. the auto brightness detection device causes drain from constantly adjusting or recalculating the brightness to display, even when screen is off. Seems like display can have a huge drain even when the screen isn't on.

2. The radio is constantly switching between 3G/HSDPA or trying to connect and cause drain even when phone is idle. Could be the same with the wifi constantly sending / receiving packets between itself and the router.

3. Voltage management is poorly written in the kernel:
[Nexus One Q&A, Help & Troubleshooting] OferR:
Reporting back...

My WiFi has always been on Never, but Android OS was draining the battery.

Switched WiFi to 'Never when plugged in' --> No effect.

Exited Latitude, which I remember going into after installing GB, + switched off WiFi completely. --> Good performance. a bit better than Froyo.

Using recovery, wiped cache and dalvik cache, + switched WiFi to settings to 'Never' and switched it on --> Excellent performance. Much much better than Froyo.

Take your pick or try them all... ;-)
[Nexus One Q&A, Help & Troubleshooting] r0derich:
google, please fix!
[Nexus One Q&A, Help & Troubleshooting] Jgobeil:
No problem here. In fact battery performance has improved.

I disabled Latitude and set Wifi to Never. My phone is unlocked and rooted.
[Nexus One Q&A, Help & Troubleshooting] galaxys:
Haven't seen any negative battery performance...it seems a little better than Froyo.
[Nexus One Q&A, Help & Troubleshooting] psroberts:
I think the solution might be to wipe the cache using recovery mode. I've struggled with poor battery life since the update, with Android OS always running at between 20 and 50% CPU usage. I cleared the cache yesterday and immediately the CPU usage by the OS dropped to between 3 and 7%. The phone has gone from not making it through the day to the battery life being at least as good as Froyo.

To wipe the cache:

-hold down trackball whilst turning on phone and wait for recovery menu.

-select "recovery mode" from the menu.

-when the android on the skateboard pops up press volume up and the power button together to get the recovery menu.

-select "wipe cache".

It takes a couple of seconds and you do not lose any data - all apps, settings, data will remain untouched.

If the issue lies with the OS cache, this explains why some are experiencing battery life problems and some are not. Presumably some part of the OS pre-compiled under Froyo and stored in the Dalvik cache isn't happy on GB.
[Nexus One Q&A, Help & Troubleshooting] r0derich:
Cleared cache seems to NOT fix it..
[Nexus One Q&A, Help & Troubleshooting] kermitdefroghere:
Fyi, wiping cache does not fix things for me.

Android os usage jumped from 2% to 8% in under an hour after half a day of overall use.

Ie. The increased android usage (with wifi on) is very drastic.
[Nexus One Q&A, Help & Troubleshooting] InertAgent:
Wiping the cache didn't work for me either. Android OS is back up to 29% after a few hours. I'm back to the "Wi-F settings->Wi-Fi sleep policy->Never" workaround.
[Nexus One Q&A, Help & Troubleshooting] deetwo:
Running warm

Same here; Stock N1 and much worse battery life since update. I keep my phone in a leather holster (ala Blackberry sleeve) and I've noticed that since the update it is much warmer when I remove it from the holster. Something is obviously not sleeping properly when the screen is off.
[Nexus One Q&A, Help & Troubleshooting] DRO4LIFE:
I have the same issue with my Nexus One (Gingerbread). It's much warmer, even when in my pocket, and the battery life is being drained by the Android OS process.

I just wiped my cache, so we'll see if that works, but to be honest, I'm wondering if it has something more to do with the most recent Google Maps update and not Android. I updated to Gingerbread manually, and don't recall the issue during the first couple of days. Then, I went into the market and updated my installed apps, Maps being one of them. It seems to me that the issue was more prevalent after updating some apps, and with Maps being so integrated, and new features that are using location data, I wonder if the Maps v5.2 is actually the culprit. Can anyone who's more technical take a deeper look into it and verify if this might be the case?

Thanks!
[Nexus One Q&A, Help & Troubleshooting] lnxpowa:
Im having issues with battery, it only lasts one day tops, but on my case its the display taking all the juice (61%)... Android OS is stable at 2%.

Anyone else having the same issue? Is it a known issue? (btw I have the amoled version of N1)
[Nexus One Q&A, Help & Troubleshooting] cjd888:
Had the same issue, would drain the battery overnight with android OS showing as top battery user.

Setting the wifi to never sleep seems to have fixed it for me, lasted all night with only a few percent drop in charge.

I have wifi turned on all the time and an active wifi router for it to stay connected to.
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
yeah wifi set to "never" has always been the better battery saver, by leaps and bounds. from the battery app i wrote, i hacked together some 2-second polling graphing and compared wifi to 3G for such tasks as receiving an email, loading a web page, etc. and wifi barely hit the current draw. but the same email coming thru, not even opening it just seeing the notification appeear and download, the 3g current draw spikes thru the roof.

i think it is all lag times. wifi has such fast ping and low latency, where 3g will ramp up the radio and take longer to do the same task.
[Nexus One Q&A, Help & Troubleshooting] agorapho99:
So after my upgrade to 2.3.3 stock via custom recovery from 2.2.1 (German T-mobile), I had exactly the same battery draining problem described here, losing about 20% in 4 hours and with Android OS being the major culprit with 40-50% battle use.

All of this is gone now and these are the things that I changed:

1.: Reboot via recovery image as described in this thread

2.: Set wifi turn off settings to "Never" (see thread)

3.: deactivated juice defender, which I thought might not be 100% compatible with gingerbread power management.

4.: turned the automatic brightness and GPS off and on again with the power widget, although I tend to keep my GPS manually off when I don't need it.

Notes:

1.: After installing gingerbread I used Mybackup to get my apps and data back still I had about 100 legacy apps installed if which I didn't know for sure whether they were working with GB.

2.: I have the newest Google Maps installed and there is NO issue.

3.: I can't tell you which on of the things above did the fix (will look into that), but my suspicions are on juice defender or the wifi policy (although I doubt that Google wild have missed such an obvious bug a the wifi policy). I would trial this with a completely vanilla install, but I have no way to make a full backup/image as I have no root and my bootloader stays locked. Will play a little with the changes I made above though an report back...

Well, hope this helps...
[Nexus One Q&A, Help & Troubleshooting] bobbyphoenix:
Well I don't know what change, but I was getting pretty good life (about two days), but I was using Go weather, and it started to mess with the phone, so I took the widget off, and cleared the data. I played around with some other settings (I wish I wrote them down) , and today life is insane! So far four hours and it dropped from 100% to 98% with some texts, and 45 min of words with friends. Wow! I'm happy.
[Nexus One Q&A, Help & Troubleshooting] bobbyphoenix:
Well I just went over 1 day. Only down to 63%. I'm not touching my settings anymore.

[Nexus One Q&A, Help & Troubleshooting] Rusty!:
So how are we supposed to see what's stopping the phone from sleeping now?

I woke up to this this morning:

I miss the battery history menu :(
[Nexus One Q&A, Help & Troubleshooting] haturaya:
I'm so frustrated with 2.3.3 performance... riddled with bugs

1. Exchange email not pushing any email,

2. screen auto brightness that seem to stuck with high bright even though the ambient light drop,

3. Awake issue that I can't figure out why,

4. Wifi wake setting, etc)

Reverted back to 2.2.2 FRG83G. I need reliable phone more than 'extra' GUI effect... For me 2.3.3 more cosmetics than functionality / stability.

Enough said... I'll wait until better / stable version comes.
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
if you look at your long awake time, it coincides EXACTLY when you lose signal for a brief period of time, shown in red. i am willing to bet this is the bug in gingerbread where once the phone loses signal, when it re-acquires it it has problems. seems to me like it caused your phone to stay awake from that point forward, killing your battery.

we need more people's results.
[Nexus One Q&A, Help & Troubleshooting] Rusty!:
Interesting, it lost signal briefly as I switched from 3G to 2G over night.

More results would indeed be handy.
[Nexus One Q&A, Help & Troubleshooting] jonesy420:
notice when the screen goes off the wifi was turned off and you lost signal at the same instant (maybe a coincidence, maybe not.) now the phone should have gone to sleep at this point but something kept it awake. it seems that there is a bug in gingerbread with the wifi sleep policy. after some searching i found there is a workaround. go into Settings->wireless&networks->Wifi settings->[press menu]->Advanced and change wifi sleep policy to "never." now the battery will last considerably longer. I did this and now my battery can go 2days+ on standby. just remember to turn wifi off when youre not using it.
[Nexus One Q&A, Help & Troubleshooting] sandman_rave:
I found a trick, reding through some forums, that seems to save your battery life quite a bit.

It seems like the AMOLED displays use a lot of battery when they have to display a white or very bright image and very little battery when displaying a black image.

So, I changed my wallpaper to a black one (this is very nice since you can also lower the brightness of the display because you have better contrast on black).

I will post back in a few days with the result but so far it seems to do the trick.
[Nexus One Q&A, Help & Troubleshooting] apollofroyo:
does gingerbread really has bad battery???
[Nexus One Q&A, Help & Troubleshooting] sandman_rave:
Considering it's an 11 page thread with people complaining about the battery I would say yes :P.
[Nexus One Q&A, Help & Troubleshooting] RogerPodacter:
this trick has been posted long ago. amoled screns use no power to show black colors. so you should use black everywhere possible. this is why the cyanogen browser has an "invert color" option to make all web pages black rather than white. etc etc
[Nexus One Q&A, Help & Troubleshooting] haturaya:
Yes for my N1. That's why I revert back to FRG83G 2.2.2

Will move to Gingerbread when they rectify the problems.
[Nexus One Q&A, Help & Troubleshooting] sarshadd:
So it seemed as though my battery life was the same if not better up until around this past Weekend...

I tried to sideload a copy of SMS Bomber that had a fairly robust set of permissions. It looked different than the copy my friend was running and it always force quit so i uninstalled it immediately.

Anyway, after noticing a battery decline I restored my phone and reconfigured everything. Battery life has been the same if not worse. I could get through a full 12 hours and end up around ~40/30% with hard use. Now it's been only 14 hours and I'm already at 19%.

My phone has been asleep in my car for most of the day and I used GPS on maps (which I would enable/disable before entering/exiting maps) for MAYBE 10 minutes. Display used 61% and cell stand by and maps both used 11% so nothing stands out.

Something I've noticed in the logcat of late that I didn't really notice before was A LOT of

I/System.out (app ###) [INFO:##] f: runnning flush

I/System.out (app ###) [INFO:##] f: sending payload

and the app or process that was always responsible was com.google.process.gapps (com.google.android.gsf) with NetworkLocationService (com.google.android.android.apps.maps) coming in as a close second.

Normally it would just be a whole load of D/dalvikvm freeing resources, but these google app processes were checking in ever 10-15 lines on the logcat.

Any ideas?!
[Nexus One Q&A, Help & Troubleshooting] wulfnuts:
i had pretty bad battery life with 2.3.3 too
[Nexus One Q&A, Help & Troubleshooting] Indomatic:
This is the same problem I have.

It was even worse though with juice defender.

I just switched my wifi policy setting so I'll have to see if it changes it.
[Nexus One Q&A, Help & Troubleshooting] :
I am having the same issues. I have my wifi off, my GPS off and i have actually deleted apps like Twitter and a few random ones i had. Battery life still has issues. With mine i have noticed that the display is taking up about 70% of my battery :( everything else that is running is 9% and under and my OS is running at 3% on average. I dont have my auto brightness on, and i have the brightness set pretty dang low. So i guess i still need to find out why my Display is sucking up so much battery life. I will try running a darker background then i already am and see. But if anyone else finds ways to get the display to stop sucking up so much percentage that would be awesome!!
[Nexus One Q&A, Help & Troubleshooting] haturaya:
You minght want to try brighter background wallpaper if your N1 is using SLCD screen.

Thanks ill give that a shot. I actually changed my theme today back to the system theme and my battery life greatly improved today!!
[Nexus One Q&A, Help & Troubleshooting] ar_hnazari:
Dudez and galz :p

Since some playout on my N1 retail (not from any operator) and update to GRI40, had same issue with battery life. Battery status showed 60% usage by android OS and that's awful.

Reading many forums from users some had suggested something that I dunno why but worked for me somehow.

In WiFi settings changed sleep policy from advanced setting (pressing menu when in WiFi settings) to "NEVER" now I have andriod OS usage of 2% :D but WiFi jumped to 33% from about 15%. :cool:

Now observing the battery life will report after 2-3 days of testing to see what happens.

Other settings: GPS off, Sync off, Background data off just on when needed, WiFi always on.

Note: Somewhere else I read about wiping /cache via recovery mode and also deleting and recreating WiFi network profiles. Each item improves the battery life, I did all now:

OS: 2%

System: 2%

Idle: 4%

Cell: 7%

WiFi: 8%

Launcher: 2%

Awesome ... isn't it???
